Resolution of filters' conditions should be postponed till all mappings are loaded. ----------------------------------------------------------------------------------- Key: HHH-2488 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2488 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.2 Environment: Hibernate-Version: 3.2.2.ga Java(TM) SE Runtime Environment (build 1.6.0-b105) Reporter: Dmitry Katsubo When trying to use the possibility to define the conditions for the same filters in {{<filter-def>}}, the following exception occurs, as the resolution of conditions should be done at a later stage, after all mappings are loaded: {noformat} Exception in thread "main" java.lang.NullPointerException at org.hibernate.cfg.HbmBinder.parseFilter(HbmBinder.java:2931) at org.hibernate.cfg.HbmBinder.bindCollection(HbmBinder.java:1462) at org.hibernate.cfg.HbmBinder$2.create(HbmBinder.java:2757) {noformat} The example of definition, that uses filters: {code:xml|title=clauses.hbm.xml|borderStyle=solid} <class name="ClauseFolderImpl" table="stc_folders"> <id name="id"> <generator class="native" /> </id> <property name="name" not-null="true" /> <property name="private" not-null="true" /> <set name="subFolders" outer-join="false" cascade="none"> <key column="parentId" /> <one-to-many class="ClauseFolderImpl" /> <filter name="folderFilterLimited" /> <filter name="folderFilter" /> </set> <filter name="folderFilterLimited" /> <filter name="folderFilter" /> </class> <filter-def name="folderFilterLimited" condition="(parentId is null or (languageId = :languageId and procedureTypeId = :procedureTypeId))" > <filter-param name="languageId" type="int" /> <filter-param name="procedureTypeId" type="int" /> </filter-def> <filter-def name="folderFilter" condition="(parentId is null or private = :isPrivate)"> <filter-param name="isPrivate" type="boolean" /> </filter-def> {code} As Hibernate ues DTD to check the validity of configuration file, the {{<filter-def>}} definitions can't be moved to the beginning of the configuration file. The possible walkaround is to define filters in another file, and include it first: {code:xml|title=hibernate-configuration.xml|borderStyle=solid} <hibernate-configuration> <session-factory> ... <mapping resource="filters.hbm.xml"/> <!-- only filter-def's here --> <mapping resource="clauses.hbm.xml"/> ... </session-factory> </hibernate-configuration> {code} Relative issue is [http://opensource.atlassian.com/projects/hibernate/browse/HHH-1182#action...
